Questions in vi

[Thieu Nguyen]

I am running the vi editor under a 386 based platform, with SCO Unix System V,
v3.2.2.  We deal with Megabyte size ASCII databases (30Mb to 90Mb) and have
a need to edit very large files.  At the present time vi hangs trying to open
the file.  Is there a way to increase buffer size, or is vi limited to editing
small files?  Are there any other Unix editors that can handle large files?
